Hi Chris,
There's obviously been some interest, internationally, in producing definitive standards for medical device usage and training materials, etc, given that there are working documents for training and the safe use of equipment in existence. Seems they've been knocking-around for a while.
For example:
IEC/TR 61258 Guidelines for the development and use of medical electrical equipment educational materials 1994-02 2009
This report
Outlines a generic process for developing materials for education and training of operators of medical electrical equipment. It may be used by standards organizations, manufacturers, regulatory agencies, hospital managers, physician and nurse educators, and others involved directly or indirectly in education and training of users/operators.
and
IEC/TR 60930 Guidelines for administrative, medical, and nursing staff concerned with the safe use of medical electrical equipment 1988-08 2008
This explains that
Medical electrical equipment may introduce hazards for patients, operators or the surroundings. This report helps lessen the risk of such hazards by providing a code of safe application and guidelines for administrative, medical and nursing staff, in addition to the safety measures incorporated in the equipment and installations.
It's possible that these reports, and others like them, may eventually form the basis of international standards that British Standards might stem from in the future. Meanwhile they may be a useful source of reference, as documents produced by groups of experts, for those interested in looking for a definition of such terms as "competency based training".
Hope these comments are of some relevance to your initial question(s).
